Banks (synonyms: reserves, countinghouses, treasuries; example toponyms: First Citizen’s Bank of Metropolis, the Iron Vault) are locations that deal in money. They may offer loans, a stable and safe place to store cash and valuables, or a tempting target for a heist depending on the fictional world. They are likely located in towns and cities and may contain vaults, safes, and security boxes. They are home to bank tellers, bankers, wealthy individuals, guards, bank robbers, and cat burglars.

Banks are an opportunity to introduce a fictional currency.

When designing banks, consider the security apparatus put in place to protect assets held at the bank. These may be security guards, cameras, sensors, traps, alarms, and other elements.
